NewsMicrobial cell factories may help get to the root of understudied plant molecules
A team of researchers has developed a method to produce a special class of plant hormones, known as strigolactones, at unprecedented levels using microbial cell factories.

NewsRoute of entry for Semliki Forest virus into the brain revealed, yielding brain cancer treatment hope
Researchers have shown that the Semliki Forest virus enters the central nervous system by first entering the cerebrospinal fluid and binding to a specific cell type before penetrating deeper into the brain, potentially tagging the virus as an agent for treating brain cancer.

NewsResearchers develop novel reverse osmosis membrane to reduce biofouling
Researchers have developed a dual-functional reverse osmosis (RO) membrane which demonstrates broad-spectrum, sustained antibacterial activity and resistance to various foulants, making it suitable for water purification, seawater desalination, and high-salinity wastewater treatment.

NewsGut bacteria in a chemical tug-of-war with the body
Researchers have identified a clever trick the body uses to keep gut microbial influence on the metabolism in check. In the intestines, the body modifies the microbial bile acids into a new family of derivatives, called BA-MCYs, using an enzyme named VNN1.

NewsManure management in China cuts river antibiotic pollution but raises groundwater contamination risks
A study of antibiotic pollution patterns in China’s water systems over the past decade found a 59% decrease in antibiotic pollution in rivers, primarily due to reduced direct manure discharge, but antibiotic leaching into groundwater has increased by 15%.

NewsScientists explain how a compound from sea sponge exerts its biological effects
Girolline, a compound extracted from the sea sponge Pseudaxinyssa cantharella, has been investigated for possible antitumor effects and also found to have anti-malarial effects. Now researchers have a better idea of how it works.

NewsSyringe-wielding germs could crack antimicrobial resistance crisis
Friendly germs armed with their own biological syringes and poisons could hold the key to overcoming the antimicrobial resistance crisis, according to a new study.

NewsWrong place, wrong time: Why Zika virus hijacks a protein needed for brain growth
A new study shows that the Zika virus hijacks a host protein called ANKLE2, which is important for brain development, to assist its own reproduction. Because Zika can cross the placenta, this can have disastrous consequences in pregnancy.

NewsScientists engineer substrates hostile to bacteria but friendly to cells
Researchers have created nanostructured alumina surfaces which are strongly antibacterial but can be used to culture cells.

NewsT cells’ capability to fully prevent acute viral infections opens new avenues for vaccine development
Scientists have discovered that T cells—white blood cells that can destroy harmful pathogens—can completely prevent viral infection, to an extent previously thought only possible due to neutralising antibodies.
